Polyhedral Hollow Ball is a synthesis of two hemispheres to a spherical shape, each hemisphere is composed of several half fan-shaped blades, the fan-shaped blades of the two hemispheres are staggered from each other. The advantage of this filler is larger specific surface area, so it is more used for washing tower, water treatment and CO2 equipment.

Specific Application：

Widely used in petroleum and chemical industries, alkali chloride industries, gas industries and environmental protection industries with max. 

Features:

High void ratio, low pressure drop, low mass-transfer unit height, high flooding point, uniform gas-liquid contact, small specific gravity, high efficiency of mass transfer
